It’s been more than 10 years since Katie
Holmes first played a fresh-faced teen on Dawson’s Creek, but her skin
hasn’t aged a day. Which is why we weren’t surprised to hear that she’s been
tapped by Olay to be the brand’s newest spokeswoman. The actress shared a look
at her photoshoot for the skincare line, as well as answered some of our
pressing questions about her beauty routine and the craziest thing in her
medicine
cabinet.

First and foremost, Toledo, Ohio native loves Olay because “it’s an Ohio
company, so it feels like home to be working with them,” she tells PEOPLE. “They
really mean something to women. I remember buying Olay in high school because I
wanted to look pretty.”

These days she strives to “feel beautiful on the inside and outside,” which
she achieves with exercise, water and the brand’s Regenerist cream cleanser —
though not every night, as she admits that going to sleep without washing her
face is her one skincare weakness.

And while she says she never has done a wacky skincare treatment in her life,
if you opened her medicine cabinet you might be surprised to find “a lot of
Riccola cough drops for theater and they’re kind of old. They’re kind of like
candy!” (Don’t say that too loudly around Suri!)

The star got glam for her ad with Serge Normant and his team, which you can
see in the behind-the-scenes photo above. And while we had a feeling that a girl
who answered “yum, more please” to the question “Baked, mashed or fried?” might
be pretty fun to hang out with on set, the photos of her goofing off seem to
confirm that.
